' Weattain these objects with the mechanismillustrated in the accompanying drawings in which Figure I is a plan view of our device; Fig. II is a side view; Fig. III is a front view with the hand wheels of the needle valves omitted; and Fig. IV is a secthe complete burnertip.

Similar numerals refer to similar parts throu bout the several views.

Referring to Fig. I we have an oven, ran e or furnace 1 of which|2 is the front wal and 3 is the bridge Wall or bathe-plate, the latter being desirable with this burner in order to deflect the heat upward.

Attached to the front well, within the oven, is the burner tip 4 and the oil supply pipe through the pipe 7. It will be noticed, however,, that the watersupply pipe passes through the flame in front of thetip whereby the water is converted into steam which mixes with the oil after issuin fromthe ti Hand wheel 8, is part of a nee le valve whic regulates'the steam supply, while hand wheel Q'performa the same function in regards to the oil su ply.

After the flame has expanded the thermostatic rod and automatically opened the valves 10., ll'the by-pass valve 16 should be 8 closed. 'The valves 17', Here common shutofi' valves. The by-pass is featured most clearly in Fig. III.

How the burner tip is constructed. to serve the function of a needle valve becomes 8 instantly apparent from a contemplation of Fig. IV, and but little explanation is needed beyond designation of the various parts. The oil supply in the oil chamber 18. is re ulated by the needle 19 which latter 1s 9 screwably mounted at the point 20. 21 is the stufling gland forthe valve. The steam supply in the steam chamber 22 is similarly regulated by a needle 23 having the thread- 24, and beingfpacked in the stuthng gland 9 25.
